The A-DATA G Series DDR2 800 2 x 2GB memory kit was extremely surprising. First of all, it outperformed a set of Mushkin RAM rated at DDR2 1000 but run at the same 800MHz speed as the A-Data G series DDR2 800 memory. You would guess that it just scraped by the Mushkin set, but it was surpassing it by quite a margin in some tests but just squeaking by in others. Not only did it perform exceptionally, it ran at a stock voltage of only 1.8! That is what we as enthusiasts love to see, RAM that performs great at low voltages. I was also caught off guard by how much overclocking headroom this kit had. I was able to push out 501MHz to reach DDR2 1000, and amazingly, I only had to bump the voltage up to 1.9!
